Toall whom it may concern Be it known that I, WILLIS HARcRovE, a citizenof the United States, residing at Blocton, in the county of Bibb, Stateof Alabama,

5 have inventedcertain new and useful Improvements in Steamships; and Ido hereby declare the following to be a full, clear, and

' exact description of the invention, such as will enable others skilledin the art to which 9 it appertains to make and use the same.

This invention relates to new and useful improvements in steam ships.

An object of this invention is the provision of a steam ship having anovelly constructed 5 hull of such nature as to relieve the waterpressure thereon.

Another object of this invention is the provision of a steam ship havinga hull comprising a pair of spaced sections and means 9 for propellingthe same located in the space between said sections.

A further object of this invention is the provision of a steam ship suchas described which will be comparatively simple and in- 5 expensive tomanufacture, reliable and eflicient in use and readily operated.

With the above and other objects in view, this invention resides in thenovel features of construction, formations, combinations andarrangements of parts to be hereinafter more fully described, claimedand illustrated in the accompanying drawings, in which Figure 1 is aside elevation of my invention. Fig. 2 is a longitudinal sectional viewthereof. Fig. 3 is a transverse sectional view taken on the line 3-3 ofFig. 1, and Fig. 4 is a transverse sectional view taken on the line 4-4of Fig. 1.

Referring to the accompanying drawings by similar characters ofreference throughout the several views, the numeral designates generallymy improved steam ship which comprises a hull 11 consisting of a pair ofupper and lower sections 12 and 13. L5 The lower section 13 comprises adeck 14 and a b0ttoml5 curved in the usual manner and having oppositesides connected thereto by the usual longitudinally and transverselyextending ribs 17 and 18, respectively. A plurality of verticallyextendingstandards 19 are secured within the lower section 13 of thehull and extend upwardly through the deck 14 as clearly illustrated inthe drawings. The section 12 comprises a deck 20 and a bottom 21connected by the usual sides 22 which are curved toward their op ositeends to conform to the curvature of t e sides of the lower section 13.

The deck and bottom 20 and 21 are formed with alining openings throughwhich are extended the standards 19 and connected by the usual braces23.

A plurality of standards'24 are secured to the opposite sides of thebottom 21 and extend upwardly through openings formed in the deck 20.These said standards 24 are suitably connected to the sides 22 of thedeck 12 by brace rods 25. An upper deck 26 is secured to theintermediate portions of the standards 24 and upper portions of thestandards 19 and extends substantially parallel to the deck 20. A top 27runs in parallel relationabove the deck 26 and is secured at itsopposite end to the adjacent terminals of the standards 19,

while slanting downwardly from the opposite ends of the top 27 areinclined tops 28 which are secured to the intermediate portions of thestandards 24 slightly above the adjacent ends of the deck 26. The bottom'21 at intervals throughout its length is formed with a plurality oflongitudinally extending slots 29 through which extend propeller wheels30 which are keyed upon shafts 31 journaled in suitable bearings 32secured to the upper face of the bottom 21. These propeller wheels 30are operatively connected as indicated by the numeral 32 to an engine 33by means of which a rotary movement is imparted to the propeller orpaddle wheels for the purpose of driving the vessel.

When the hull 11 is immerged in the water the line of the latter will atall times remain slightly above the upper side of the wheels 30 asindicated by the dotted line 34 vupon Fig. 1 of the drawings.

From the foregoing disclosures taken in connection with the accompanyingdrawings it will be readily seen that a vessel of the nature describedwill be provided for which will fulfil all of the necessary requirementsof such a device.

It should be further understood in this connection that various minorchanges in the details of construction may be resorted to within thescope of the appended claims without departing from or sacrificing anyof the advantages of the invention.

Having thus fully described this invention what I claim as new anddesire to by Letters Patent, is:

1. In a vessel of the class described the combination of a completelysubmerged hull, a surface hull, means ri idly maintaining the two hullsin spaced re ation, the surface hull having a series of slots formed inthe protect bottom thereof, a paddle wheel workingdiln' e each slot,andmeans for driving the pa wheels. I 2. The combination with asubmerged hull, of a surface hull having a series of slots formed in thebottom'portion thereof, means connecting the submerged hull and surfacehull in spaced relation, 9. series of.

dle wheels.
